EDA Market: Three Countries Stand on Each Other and Maintain a Relatively Balanced Pattern

Sharp tools make good work. Today's chip design has reached 100 million gate level integration, and even the most experienced design engineers can't complete it by hand. In the process of chip design, simulation verification is a very important link to ensure that the chip meets the expected design performance requirements before entering the production process.

EDA industry, which provides simulation and verification tools for chip design engineers, is the most upstream and high-end node in the ecological chain of the whole semiconductor industry.

The global EDA market is basically dominated by three companies: cadence, Synopsys and mentor graphics

Mentor graphics, the smallest of them, has been acquired by Siemens. After more than 30 years of industry development and market competition, these three major EDA suppliers have their own unique advantages and maintain a relatively balanced pattern in the dynamic changes of global semiconductor technology and market.

The three EDA suppliers can provide a complete set of chip design solutions, including a complete set of design tools such as analog, digital front-end, back-end, DFT and signoff. Cadence's strength lies in analog and mixed signal simulation and layout design, but its signoff tool is weak. Synopsys has the advantages of digital front-end, digital back-end and ptsignoff, while mentor has the advantages of calibre signoff and DFT.

In addition, candence and Synopsys also provide IP authorization (hard core and soft core), which is very attractive to small and medium-sized design companies. Authorized IP usually includes hard cores with relatively high R & D costs or thresholds such as memory, SerDes and power management.

What Are the Advantages of LED Light Source DLP Splicing Products
As a new large screen video technology, LED light source DLP splicing products have always been one of the key industrial innovations concerned by the industry. The adoption of sub era light source LED technology is not only a simple change in light source technology, but also will fundamentally change the practical performance of DLP splicing products, and even create many new application modes. So, what unexpected new surprises will the new LED light source DLP splicing bring to industry customers?Lower system cost of ownershipThe first significant change in the application of LED light source to DLP splicing wall products is that the cost of users is significantly reduced. Although the use of LED technology will increase the first investment of DLP splicing wall project by 30%, the service life of LED light source reaches 60000 hours, which is about 20 times that of traditional mercury lamp. In other words, the customer's lifetime hit on the DLP splicing wall will save at least 20 bulb replacement costs. This cost can not only offset the increase of DLP splicing unit cost caused by LED technology, but also "save a lot of investment".Another feature of LED light source technology is that the three primary colors emit light independently. This makes the DLP projection system no longer need the previous color wheel beam splitter. As a mechanical operation product, the maintenance and replacement frequency of color wheel is also an important part of customer cost. Although color wheel components are not the core consumables of DLP splicing wall, the economy of LED light source products without color wheel can not be ignored.The long-life LED light source also greatly reduces the maintenance frequency of DLP splicing wall. The annual maintenance quantity can be reduced by at least 50%. This will also serve as an important "money saving" node and become one of the important added values for customers to purchase LED light source products. In addition, as an efficient light source product, LED will also bring higher luminous efficiency and higher light utilization, thus reflecting another part of the "low-cost" characteristics of saving electricity.Higher system reliabilityLED light source products are solid-state cold light source products. The utility model has the advantages of high working efficiency, low heat generation and less accidental damage in solid state. The traditional mercury lamp light source has the same vulnerability as an ordinary electric bulb. Its product temperature is very high in the high-light working state, and it is more likely to be damaged, burned or burst due to accidents. The solid-state emission of LED light source significantly increases the stability of the light source itself.Different from traditional mercury lamp products, LED light source is driven by low-voltage DC pulse. The power supply part does not contain high voltage and high current components, so the service life and stability of the power supply are more controllable. Combined with the natural luminescence of the three primary colors of the LED light source, there is no need for mechanical color wheel components for light splitting, which makes the LED light source more stable than the traditional mercury lamp in terms of power supply, control and light splitting.The three primary colors of LED light source work independently, which also makes the whole machine can still display the picture in the lack of color even if a "bulb" fails. This is in sharp contrast to the situation that the traditional single lamp DLP splicing unit cannot work once the bulb is burned out. It can display without color, so that once the light source appears unexpectedly, the LED light source can minimize the loss of customers to the greatest extent, or even no loss. Compared with the simple single lamp DLP splicing unit, the reliability of LED light source products is closer to the dual lamp backup system.Green environmental protection and low carbonLED light source technology is a famous green environmental protection technology. The characteristics of its semiconductor process make it easier to control toxic metals. Unlike the traditional mercury lamp, once damaged, it is likely to cause the leakage of toxic elements in the internal mercury lamp. As a semiconductor element, LED light source can also be recycled, and important metal elements can be recycled in the smelting process again.In addition, LED light source products are also light source products with high luminous efficiency.Under the same brightness conditions, it has lower energy consumption. Moreover, the LED light source emits light in digital pulse mode with independent three primary colors. The LED light source works only when the DLP light valve chip DMD needs light of a certain color. This is quite different from the continuous ignition mode of the traditional mercury lamp. LED light source does not work continuously. It only makes valuable luminescence when needed, which also makes it better meet the needs of low-carbon and environmental protection for future economic development.Bright colors make the picture more gorgeous
